Answer:
Step-by-step explanation:
Let the number of blue marbles be x
The number of green marbles = 3x - 2
Total marbles= 18
x + 3x -2 = 18
4x - 2 = 18
4x = 18+2
4x = 20
x =20/4
x =5
The number of blue marbles = 5
The number of green marbles = 3*5 - 2 = 15 -2 = 13
1.24
3.56
7.89
Really any number that has a decimal (period in it)
Answer:
MAD = 2
Step-by-step explanation:
<u><em>First We'll find the mean of data</em></u>
Mean = 
Mean = 4
<u><em>Then, we'll find absolute deviation</em></u>
=> |4-3| = 1
=> |4-2| = 2
=> |4-1| = 3
=> |4-1| = 3
=> |4-3| = 1
<em><u>Now, taking the mean of these absolute deviations:</u></em>
MAD = 
MAD = 
MAD = 2
Answer:
Option A - 
Step-by-step explanation:
Given : Expression 
To find : What is the value of the expression ?
Solution :
Step 1 - Write the expression

Step 2 - Applying symbol rule i.e. multiplication of positive into negative is always negative, 

Step 3 - Solve

Therefore, The value of the expression is 
So, Option A is correct.
<u>Answer:</u>
The great common factor is:
<h2>
x(2z)²</h2>
<u>Steps:</u>
given:
4x²yz³ = 2²x²z²yz
4x²yz³ = <u>x(2z)²</u>xyz
---------------------------------
12xz² = 4×3xz²
12xz² = 2²3xz²
12xz² = <u>x(2z)²</u>3
The great common factor is: x(2z)²
